Effect of temperature on the mechanical properties of aluminum polycrystal using molecular dynamics simulation

Case Studies in Thermal Engineering
The initial temperature has a considerable effect on aluminum polycrystals' physical stability and mechanical performance, with the possibility to optimize their mechanical properties for practical applications. Thus, using a molecular dynamics technique,

Effect of sintering cycle on the strength and translucency of multilayered zirconia

Journal of Prosthodontics, Volume 35, Issue 8, Page 1350-1357, October 2026.
Abstract Purpose A newly introduced sintering protocol promises to offer higher translucency while not significantly compromising the flexural strength of the material. However, the effect of the novel sintering protocol has not been thoroughly validated.

Envejecimiento y propiedades eléctricas de materiales basados en Y-TZP

Boletín de la Sociedad Española de Cerámica y Vidrio, 2002
The electrical response of 3mol% yttria tetragonal zirconia polycrystals (Y-TZP) was measured as a function of the grain size in the low temperature range (T < 350°C). The impedance spectrum shows two peaks related to grain and grain boundary effects (

Effects of low‐pressure plasma and ytterbium fiber laser on zirconia surface properties and bond strength to gingiva‐colored composite

Journal of Prosthodontics, Volume 35, Issue 8, Page 1312-1323, October 2026.
Abstract Purpose To evaluate and compare the effects of surface activation by low‐pressure plasma (LPP) and surface texturing by ytterbium fiber laser (YFL) treatments on zirconia surface properties and shear bond strength (SBS) to a gingiva‐colored indirect composite under aged and non‐aged conditions.

Elastic Properties and Thermal Expansion Behavior of a Polycrystalline VMnFeCoNi High‐Entropy Alloy

Advanced Engineering Materials, Volume 28, Issue 18, 23 September 2026.
The high‐entropy alloy (HEA) V20Mn20Fe20Co20Ni20 (composition in at.%) can be made single‐phase face‐centered cubic (FCC) when annealed above 1338 K followed by water quenching. In this state, the alloy exhibits the greatest strength‐ductility combination of any quinary single‐phase FCC HEA.

Phase Field Failure Modeling: Brittle‐Ductile Dual‐Phase Microstructures under Compressive Loading

Advanced Engineering Materials, Volume 28, Issue 17, 9 September 2026.
The approach by Amor and the approach by Miehe and Zhang for asymmetric damage behavior in the phase field method for fracture are compared regarding their fitness for microcrack‐based failure modeling. The comparison is performed for the case of a dual‐phase microstructure with a brittle and a ductile constituent.

Triple Junctions as Dislocation‐Like Defects: The Role of Grain Boundary Crystallography Revealed by Experiment and Atomistic Simulation

Advanced Engineering Materials, Volume 28, Issue 17, 9 September 2026.
Grain boundary triple junctions are an essential ingredient of the microstructure of polycrystalline materials. In this study, a triple junction is observed using atomic‐resolution scanning transmission electron microscopy and characterized. Computer simulations reveal that the junction has a dislocation character that is determined by the joining ...

Influence of Inhomogeneous Plastic Strain and Crystallographic Orientations on Fatigue-Induced Dislocation Structures in FCC Metals

Metals
Owing to the differences in crystallographic orientations among individual grains, dislocation structures in polycrystals are inherently inhomogeneous from grain to grain.

Approaching crystal’s limit of thermoelectrics by nano-sintering-aid at grain boundaries

Nature Communications
Grain boundary plays a vital role in thermoelectric transports, leading to distinct properties between single crystals and polycrystals. Manipulating the grain boundary to realize good thermoelectric properties in polycrystals similar as those of single ...
